[ANN] [QRK] Quark | Core 0.10 upgrade

[zvs]

QfJNcqsWbZ6hi1bxVhQEqCm3kPyHeR6juF just started and found block:

QfJNcqsWbZ6hi1bxVhQEqCm3kPyHeR6juF: 5.12
QfD5gf3Xqnj1PWN5xFp4dbsehkwmcJ5vX5: 63.10611
Qb1VvQJorRQmJB41Rfzu82HUXrytKFNTPE: 955.77388

that's crazy...  so, after that matures, i'll send 500,  seems only fair, haha

As the supply gets reduce it should have a better price, hopefully.

You can try ALPHA stratum pool here:

Stratum Port: 6010

fee is now 0% but will raise to 1% later on

Hi folks,

sorry for being so rare, but i have to much stuff going around currently and in the next weeks.

Cool, the more nodes the better!  

Do you guys think I should put Neisklar's node as bootstrap addres? Maybe it is wiser to have a number of separate p2pools so that users get fewer but higher payouts, minimizing tx fees.

Just so you know. I blocked the peer port on my pool, you can't use it as bootstrap.
At first that was during the setup, testing and so on, to be just on a save side, but later on i'm in the opinion that it's better to have more seperate p2pools.

Why?

1) If we have one big p2pool network, or have many "isolated" p2pools nodes, that is the same regarding decentralization.
The important part is (although fewer fee's for me ;-) but that's no problem, i did that mainly for fun and providing some push for the coin) to have pools operated by different people.

2) The wallet hase problems with large transactions. Large doesn't mean high amount of QRK, it means high amount of inputs.
If we have one big p2pool network the block reward is distributed about all nodes, means even more smaller payouts to slower miners.
Then when sending a amount, the wallet first tries to assemble that amount of many smaller amounts (the inputs) you received earlier, this resulting in large transactions.

If i'm wrong with my opinions, please feel free to show me my errors in my thinkings.



BTW if you have high hashing power you shouldn't use a pool. You only make it more difficult for slower miners.
Just take a litecoin calculator, take the QRK-diff DIVIDE it by 256 and use that diff in the calculator. If you see that you will get a block in 2 or 3 hours, thats ok, don't use a pool. At least in my opinion.


I'm to lazy to do proper quotations.
Next topic is miner optimizing:

Please have a look at this site:
http://bench.cr.yp.to/primitives-sha3.html
http://bench.cr.yp.to/primitives-hash.html

There you will find DETAILLED comparision AND OPTIMIZED code of the used hashing functions for different platforms, cpu instructions sets and so on
I'm sorry to say, but currently i don't have the time to work on a quicker miner, and some people already did some really good optimizations. My last tries also produced mostly errors so i'm in the hope the cpu miner for quark is a good starting point so that more experience people when it comes to optimizing, and assembler stuff can produce some really great miners.

(Personally I would like to see one W64 with sse4 and AES support;-) )

Here is also some halfway good list of supported instructions sets by different cpu's

Great post, my thoughts exactly. Post your QRK address already so ppl can tip you! 

[Neisklar]

Yeah, when i'm back at work next week, need to get my main address:)



I have no idea what the blockexplorer problem is, so i will reset the database of the blockexplorer (not the pool) and let abe reimport all stuff.
Hopefully that will fix all issues. If not, maybe quarkcoind's database is out of sync

When I searched the error it seems to relate to network reviewing blocks or of order or orphans confusing Abe.  Was supposedly fixed 7 months ago on bitcoin Abe are you perhaps using an outdated fork?

No, thats relativly up-to-date. (2 or 3 wekks)
But it was maybe that every FastCGI instance started was trying to import, and the database got inconsistent.
Now FastCGi won't import, and the dataimport does now a cronjob, which runs every minute (so it may that not always the newest block is visible)
(Hmm,  it may also since the quaktcoind used for the blockexplorer is the same as the one from the p2pool instance. I will later seperate them)

@all:

The Blockexplorer is working again.


Edit:
@other p2pool operators:

On the stats page of the pool i regulary have some spikes going to zero, i think if had had read the forum correctly, then also there is no connection to the miners. If you find a solution, please share it.

[eule]

Yeah i saw that, maybe too many connections or quarkcoind used too much cpu? Or the too many files open error, I have that on my yacpool sometimes if I forget ulimit -n 1000000.
Have you seen what p2pool reports during those times, if anything? My yacpool sometimes is not reachable for a short time (~5 min) from browsers, but p2pool keeps running fine and miners submit work if i go check, I think that happens when yacoind uses a lot of CPU.

Anyone knows how to solo mine with the minerd?

Same as a pool but the information comes from quarkcoin.conf and you must have the daemon running
-o 127.0.0.1:rpcport
-u rpcusername
-p rpcpassword

Code:

./minerd -a quark -o 127.0.0.1:11973 -u <rpcusername> -p <rpcpassword>

Throws connection error:

Code:

I will did into the log and hope thats not already rotated out.

Also there are still some corrupt miners which submit shares above target, it looks like it's reporting all it calculates:

QP967T5PavPKNdFm4ctqxLdbLMhECU5uoZ

If i were better in Python i would implement a temporary IP ban for such clients, so the clients get some notice.
Or is there a way to pass some messages to the miner with stratum and/or http RPC?

[Kryon]

pls add the official compiled a miner in the first message. Many people do not know how to compile the source code.

You can try ALPHA stratum pool here:

http://qrk.coinmine.pl
Stratum Port: 6010

fee is now 0% but will raise to 1% later on

typo

Getting Started
If you use a command-line miner, type:
minerd -a quark -o stratum+tcp://a{HERE  need q}rk.coinmine.pl:6010 -u worker_name.1 -p password

 minerd -a quark -o stratum+tcp://qrk.coinmine.pl:6010 -u worker_name.1 -p password

Mining in a pool is kind of nessesary now.

[ex_mac]

Hi,

new p2pool

http://109.205.247.150:8372/static/
in test mode now

Change the port to 9000 when running minerd.

Sorry, it was a typo. Still doesnt work, throws the same errors.

Try rpcallowip=* and use -o localhost:9000 instead of 127.0.0.1

How do I move all my the coins I got from the P2Pool to a different address? All I get is transaction too large, etc errors.

Send several small transactions the client fails if the transaction has too many inputs

This will be fun moving 200k coins then... 

If you send me your wallet.dat I would be happy to move them for you

[paymetodostuff]

What does adding the -salvagewallet do?

-salvagewallet will rescan your wallet transactions in the blockchain, and recover any coins that you attempted to send out, but the transactions did not confirm.

be sure to backup your wallet first

I've had to -salvagewallet multiple times to recover coins since using the p2pool.
